Use encrypted string in URL

[eluser]darrenm[/eluser]
Hi there

I wan't to disguise a database ID in a url so that instead of /orders/view/123/ I have /orders/view/ENCRYPTED/ where ENCRYPTED is $this->encrypt->encode(123).

Problem is that the resulting string contains characters that are not allowed by default in URLs - and I don't really want to change the allowance.

Does anyone know of a way to get two-way encryption that only produces alphanumeric output?

thanks

Convert it from 10 to a 36 base.

edit: forget it, I read again, you want encryption.

Funny that. I wrote two functions earlier today to deal with the exact same problem. http://ellislab.com/forums/viewthread/107741/.
